What is the difference between text and html in jquery
1. html() method
This method is similar to the innerHTML attribute in JavaScript. Can be used to read or set the HTML content in a certain element
In order to display the effect more clearly, change the HTML code of the
element to:
<p><strong>你最喜欢的男孩子是?</strong></p><p></p>
Then use the html() method to
element to obtain:
var p_html = $("p").html(); //获取<p>元素中的HTML代码alert(p_html); //打印</p><p>元素的HTML代码</p>
After running the code, the effect diagram is as follows:
Get the HTML code of the entire p element
If you need to set the HTML code of an element, you can also use this method, but you need to pass a parameter to it. For example, to set the HTML code of the
element, you can use the following code:
$("p").html("<strong>你最喜欢的男孩子是?</strong>"); //设置<p>元素的HTML代码</p>
Note: The html() method can be used for XHTML documents, but not for XML documents.
2. text() method
This method is similar to the innerText property in JavaScript and can be used to read and set the text in an element. content.
Continue to use the above HTML code:
<p><strong>你最喜欢的男孩子是?</strong></p>
Use the text() method to obtain the
element:
var p_text = $("p").text(); //获取<p>元素的文本内容alert(p_text); //打印</p><p>元素的文本内容</p>
After running the code, the effect diagram is as follows:
Only displays text content, does not include and display html code
Same as the html() method, if you need to set text content for an element, you also need to pass it a parameter. For example, to set the text content of the
element, the code is as follows:
$("p").text("你最喜欢的男孩子是?"); //设置<p>元素的文本内容</p>
Note: (1) The innerText attribute in JavaScript cannot run under some versions of Firefox browser, and jQuery The text() method supports all browsers.
(2) The text() method is valid for both HTML documents and XML documents.
Summary:
1. When the html() method gets and sets the element, it sets the HTML code
2. When the text() method gets and sets the element, it sets the The text content of the element
3. The html() method does not support xml, and the text() method supports html and xml

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.

React is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.
